Hi, I am testing a new CX7 card. when i trying to link up cx7 (ip link set cx7 up), mlx5 kerenl driver repoted async reg mr failed.status -121. It seems like MLX5_CMD_STAT_LIM_ERR, but I cannot get more information from open-source mlx5 driver code.

It not happens every time when I link CX7 up. After reporting, ip tools can still scan CX7-eth port, but link status is “down”. I should reboot OS and try again.

My mlx5_core driver is complierd from linux-6.6.1 and fireware version is 28.43.1014.

Another CX6 card is pluged in the same environment, it can work normally.

Please give me some suggest to avoid this problem
